This is because the code enabled by XOR_BLOCKS (crypto/xor.c) runs a benchmark, which takes some time. It doesn't take *that* long, but it got noticed as a regression nonetheless, and it needs to be fixed. My patch series happens to have fixed this, but I didn't have it mind that it was a real bug fix. Herbert, any chance that you could send my patch series to Linus without waiting for the next merge window, so that it can be backported? - Eric
